The latest nectarine grafting, nectarine grafting tips

Nectarine is actually a variety of ordinary peaches, so it is grafted by ordinary peach trees, and plum trees are generally used as rootstocks. Ordinary peach branches are used as scions so that nectarines will grow after grafting. So what is the specific grafting method, what are the key points to pay attention to, and how should it be managed and maintained? now let's learn about the specific grafting methods.

1. Preparatory work

Choose pure and unmixed peach trees, and take the branches of robust peach trees as scions. The upper outer branches free from diseases and insect pests were used as scions. After the scion is removed, it should be stored in sand to keep it fresh, or transported. Choose a seedling with a thickness of about 0.5 cm as a rootstock, with a height of about 30 cm. Rootstocks are also healthy saplings free of diseases and insect pests.

2. Grafting method

Budding is carried out in August, first remove all the buds within 15 centimeters from the base of the rootstock to avoid competing for the nutrition of the grafted buds. Improve the survival rate. T-shaped budding. Cut a T-line cut on the rootstock, the cut depth is to see the green layer, cut an oblique knife from the scion to take the bud, and then connect to the rootstock incision, bind the incision to expose the bud. The cutting method is to cut the rootstock directly at the 2/3 section, about 1.3cm. The scion leaves several buds, the lower end is obliquely cut into a 2 cm cutting surface, and the back is cut into a 1 cm cutting surface, and then inserted into the rootstock and aligned with the cambium. Just tie it up.

3. Maintenance and management

The newly grafted buds have poor ability to survive the winter, so if they are grafted in autumn, they can not be untied to help them survive the winter, and they can also be watered to keep warm and prevent the cold before winter. Cut the anvil in the spring, and then begin to unbind. Buds will sprout after cutting the anvil, so it is necessary to remove these buds in time to ensure the growth of buds. Watering began in summer and fertilization was combined. 20 jin of urea and 30 jin of phosphate fertilizer were applied to one mu of land, with emphasis on controlling aphids in summer.

4. Seedling pruning

Buds are grafted to produce plants, and then the accessory shoots at the base of the plants are removed after entering autumn, and the shoots that continue to grow can be removed in September. The grafted seedlings are sparse in planting, and the row spacing is widened, so it is easy to plant seedlings with soil. Grafted seedlings are half a meter high to pick the heart, there are several branches to leave the main branch, the main branch to pick the heart, other branches are removed.

Nectarine is a variety of common peach trees after grafting, there are many ways of grafting, mainly introduce bud grafting and cutting. Grafting is very important to prepare and support the families after grafting, which is the key work to determine the survival rate.
